- A heat wave across parts of Texas forced the state's grid operator to call for energy conservation on Tuesday and sent electricity prices soaring past $9,000/MWh.
- The Electric Reliability Council of Texas (ERCOT) issued an Energy Emergency Alert (EEA1) around 3 p.m., when operating reserves dipped from at least 3,000 MW to below 2,300 MW. Grid conditions returned to normal operation by 5:30 p.m., officials said. It was the first time since January 2014 that ERCOT has used the alert.
- ERCOT officials had forecast a tight supply-demand balance heading into the summer, and in March said there was a growing chance it would need to utilize emergency alerts during times of high demand. NRG CEO Mauricio Gutierrez had argued those forecasts were too optimistic.
